How to choose
Terrain first, then ply.
The tread families here
3 of the 5 tires at this size cluster into two families — owners pick by terrain, then ply.
Turf
The OEM pattern on most ZTRs and lawn tractors. Wide shoulders, shallow lugs — grips wet grass without tearing the lawn.
Best on: residential lawns, flat-to-moderate terrain
Kenda K502 Terra Trac4P$56.641 more in this family, in the grid above.
AG / R1 Lug
Chevron lugs. Better grip on hills and damp clay, with the trade-off of visible tracking on flat lawns.
Best on: hilly yards, wet spring conditions, hauling
OTR Lawn Trac4P$96.99Prices per tire.
Then the ply
It's about deck weight and what you tow, not speed.
4 Ply— right for most
- Residential mowing on a 42″-to-50″ deck
- Flat-to-moderate lawns, no towing
- $12 cheaper per tire at this size
- Over-spec is overkill for residential — 6-ply buys nothing on a flat lawn
If you're not sure, this is you.
6 Ply— when the deck works for a living
- Running a bagger, towing a small cart, or mowing slopes
- Commercial-fleet decks
- The penalty for under-spec is a sidewall failure mid-season
Baggers and carts: spend the $12.

Tube or tubeless — check the tire.
Tube type varies tire to tire at this size — check the Tube row on a tire's page before you order. When one is called for, the match is a 18x8.50-10 tube (TR-13 valve).
